Weight has the 1/5 of steel only, intensity is his however 5 times above. This kind of fiber that is raw material with tree can make component of car, electron defter, firmer. If cost is reduced, get popular, this kind of material even the pattern of industry of hopeful adapting data. In mix with the metal plastic in the raw material of the product such as the car that is the mainstream, smartphone, the new-style data that uses pulp to make -- fiber of cellulose accept rice (CNF) get attention fully recently. This is one kind separates papermaking raw material through cent -- plant fiber (pulp) the superfine fibber that makes. Diameter of fibrous of rice of a cellulose accept is 3 ～ 4nm only (1nm is 1 billion minutes of 1m) , 20 thousand minutes when be equivalent to hair silk about 1. Although pulp itself is not hard, but actually, the CNF root root that makes pulp is strong. Be together these CNF polymerization, can make coriaceous material. Compare with rolled steel photograph, the weight of this kind of material has his 5 minutes only 1, intensity is his however 5 times above. Can increase the strength of electronic machinery and car assembly, come true light quantify. The glamour that can distinguish use CNF with carbon fiber depends on intensity and small amount not just, still include heat to expand rate is low with temperature change is able to bear or endure get power strong. Because come from woodiness material, because of soil still can returning after this is used, the environmental negative charge that create is small. And still have the quality that passes through oxygen and moisture not easily. Though the whole world is developing this kind of material, but Japan is in lead position in a lot of respects. The fiber that speaks of Japan to have powerful competition ability all over the world kind new material, provide most representative is carbon fiber of course. This kind of material has been used at plane airframe to wait, will return hopeful to popularize car bodywork henceforth. So, whether can carbon fiber and CNF become a competitor? The answer is negative. On intensity, carbon fiber more get the better of one prepare, but CNF is folded as a result of easy turn, use is very extensive. With respect to the car character, what carbon fiber suits bodywork is light quantify, and what CNF fits the colophony such as bumper, interior trim, tire and balata part is light quantify, both can be used at different utility. And, papermaking company cultivates the wood that has large area, raw material is very rich. Accordingly, CNF need not resemble oil natural resources in that way " afraid raw material (dried up) " (Japan makes paper CNF career advance elegant travel of Qi of room endless flow to express) . Current, CNF material still is in the phase that just began sample to offer money, production methods and utility still remain to develop. Develop the dominant power of CNF, it is to have the tree that regards its as raw material already, have the papermaking company of pulp processing technique again. Papermaking company of Japan accumulated rich intellectual experience in agelong paper production, extremely the technical actual strength that fine fibre processes velar account also ranks world front row. Accuse with the big boss prince of Japanese papermaking industry with rank second Japan to make paper be a center, development competition is in turn white-hot level. Have forecast say, to 2030, dimensions will reach year of market of CNF 150 billion yen. Organic EL (electroluminescence) substrate is one of fields that hopeful uses this kind of data. What the organic EL substrate that incidental temperature changes used in the past is hot expand the vitreous material with inferior rate, but glass is easy and broken, so very bad volume produces large product. And if use colophony replaces glass, although rupture Yi Wanshe, not easily, but heat expands rate is old, be able to bear or endure the ability that accepts temperature change is weak. If uses CNF, can make up for glass and colophony at the same time the defect of these two kinds of material. Now, a few enterprises also are being developed can develop CNF adequately " pass through oxygen and moisture not easily " the utility of this one property. Beautiful king and relief printing use CNF at packaging data of purpose, considering to use a method at present. For instance, the odour of the product such as soap penetrates easily the material that pack. If be in CNF daub the surface of wrapping paper, can release in order to prevent odour not only, still can block up air enters the interior that pack, avoid the product deterioration that oxidation causes. The car decreases heavy 20kg CNF to still have another feature. After treatment becomes velar state, CNF can become " cellophane paper " . Can bend like paper fold, and strong, transparent. This one property can be in distinguish oneself of utility of solar battery substrate. To let sunshine fine long hair illuminate of nondestructive lost territory arrives the component of batteries, must want to use pervious to light material. The material such as the glass that uses now is put in brittle defect. And CNF already transparent bear fruit again, because flexibility is big, still suit to be used on curved surface. CNF besides use alone besides, OK still a few mix into are entered will increase strength in other data, final play goes out light quantified effect. Of car assembly utility light quantify demand crop is big, big also. Summer 2012, prince makes the collaboration waiting for a person of paper and Shiyehao of Kyoto college professor, development went CNF content to be in the new colophony of 10 ％ above. Compare with past photograph, the colophony data that a car uses can be reduced make an appointment with 20kg, make car small thereby 20kg. Still research makes clear, add CNF to be able to increase the wear of balata, live friendly rubber industry applying its at tire in research. Besides, CNF replaces the most data that car assembly uses likely still. The live thing that still large chemical plant is made in corn starch in research is plastic and get together the method that CNF adds in the fiber of lactic acid. After adding a few CNF to regard aggrandizement as material, although the price expensive living things is plastic and get together the dosage of lactic acid reduces an in part, intensity still can be achieved before level. Can be in the trait that retains source of 100 ％ plant while reduce cost. Every kilograms of cost or will under 1000 yen a technology makes of CNF practical change had major breakthrough, that is the production methods of the use activator that Bei Ming of Ji of Tokyo college professor's leader develops. General pulp fibrous diameter is 20 μ M about (1 μ M is 1 million minutes of 1m) , form by many CNF. The faculty that CNF and other CNF join cheek by jowl is very strong, make very hard depart firstly. The person such as Ji shellfish professor considers to discover, a kind the name is " TEMPO activator " special activator is had disclose fibrous intention. Its principle is, to put underwater pulp to add the substance such as TEMPO activator, make its react 2 hours. Undertake agitate is handled next, the surface of CNF will electrified. The surface of each CNF can contain negative electron, each other repel each other, when discharging adhesion of repulsion prep above, with respect to can successful detached CNF. Such, the extremely even, fine CNF that the diameter is 4nm can be dispersedly in water. Through about 2 hours, after pulp fiber decomposes CNF entirely, can form glue state transparent liquid, become CNF to divide powder. Although the price of TEMPO activator is as high as 1kg tens of thousands of yen, but add a quantity to be pulp fibrous only 1 ％ left and right sides, very small to the influence of totle drilling cost. The activator with identical, more low cost also is in action at present research phase. The company that teachs joint development with Ji shellfish has Japan to make relief printing of paper, beautiful Wang He. Japan makes paper will begin from October 2013, the capacity that in the cliff of city of state of cliff of county of Japanese mountain pass pragmatic Wu place develops use TEMPO activator to make CNF is produced change an experiment. Before was being booked 2015, implementation business is used change. The production method that the arrowy wild professor of Kyoto university develops is the focus of attention likewise. This is one kind uses double axis mixer to decompose fibrous technology. Visible, around CNF the development competition of efficient production method has spread out. As a kind of new material, CNF contain is worn extensive possibility, but prospective all-pervading is crucial, efficiency, utmost is produced to reduce cost in Yudigaosheng. The gel that CNF forms in water dispersedly is difficult carry, one cannot say for sure is put, it is the element of drive up cost. If can resemble paper making film euqally, roll into coils, can overcome afore-mentioned tasks not only, return hopeful to realize serial production. By Feburary 2013, prince accuses as chemical as 3 water chestnut together, take the lead in using the technology that copy paper to make CNF coil all over the world. Its foundation is normally the technology that copy paper, this technology is solution of pulp of the dump on the net that knits for the filament of micron class in the diameter, make pulp is hanged on filament, evaporate paper is formed after moisture. It is a lot of and difficult to use this technology use this technology at returning fine CNF to exist than pulp, but, accuse through shirt-sleeve prince papermaking technology, filmy processing technique, and the chemistry of chemistry of 3 water chestnut handles a technology, difficult be readily solved. Shallow Shan Lianghang says the chief researcher that prince accuses a this department of research and development: "Although cannot introduce detailed technology, but can disclosing is, through improving facility, with at the beginning of developing, compare, the time that film spends need shortened a few. And realized serial production, to commercialize strode one stride. " the cost to CNF, big Ji shellfish professor forecasts east say: "Produce those who change research to advance as the quantity, every kilograms production cost can drop probably break 1000 yen. " this is equivalent to general steel products 10 times the left and right sides. Look suddenly seem very expensive, but the 1/5 that the weight of CNF has rolled steel only, intensity is his however 5 times, consider what wait for a product in the car is light the additional cost that major effect produces in quantifying, also should not calculate too expensive. Those who be in enterprise of China, Korea pursue and attack below, the data industry front such as Japanese iron and steel, chemical, papermaking is facing brutal competition. Japanese enterprise must want banner world, development gives data of unprecedented high additional cost, throw its practical, in order to change earnings structure. Come from this meaning say, the CNF that Japanese enterprise has numerous advantage suffers fully expect. After afterwards carbon fiber, come from new material of Japan as another, can CNF realize a leap? CNC Milling
